Substation Construction Projects

Hot Line has completed substation construction projects for numerous utilities and municipalities throughout California. Here are a few of our past projects:

Bellota Substation

Linden, CA

As part of this substation construction project, Hot Line rearranged the 230kV bus and section breakers; installed a 115/230kV MPAC control building, capacitance coupled voltage transformers (CCVTs) and potential transformers (PTs); and replaced aging equipment such as breakers, switches, insulators, CCVTs and PTs. Work was performed under our contract with ABB.

Wheeler Ridge Substation

Bakersfield, CA

Our team was tasked with increasing the visibility and automation of the Wheeler Ridge Substation through the installation of 230kV modular protection, a 70/115kV MPAC control building, capacitance coupled voltage transformers (CCVTs) and potential transformers (PTs); and the replacement of aging equipment such as insulators, breakers, CCVTs and PTs. Work was performed under our contract with ABB.
